Pokémon Data
Most all data and properties of any given Pokémon can be edited under the "Pokémon" dropdown tab within SkyTemple. From there, you can edit the data and properties of the individual gender forms of each Pokémon by double clicking on the form you want to edit.
Please note that it is generally unsafe to edit the Pokémon and "Reserve" Pokémon past #551. These are actors within the game and editing them can lead to unintended consequences. Pokémon #537 - #551 however can be safely edited and used to add new Pokémon to the game.
There are four categories of data you can edit as well as a sidebar on the left showing the Pokémon's normal portrait and a single frame from its idle animation. The sidebar also allows you to change a handful of key settings as well as import/export data for that gender form.
Settings
This data category encompasses an assortment of aspects, ranging from the displayed name to base stats to item drop rates. It is split into seven tabs.
Name
This displays the Name of the Pokémon as well as its Category (for example, Bulbasaur's Category is "Seed" because it is "The Seed Pokémon"). Both the Name and Category can be edited. On an EU ROM, there are five slots for the Name and Category, one for each supported language. Though these slots are also visible when using a US ROM, all but the English slot can't be edited.
